Journal of Inequalities and Applications, 2020 In this paper, we obtain a sharp upper bound on the spectral radius of a nonnegative k-uniform tensor and characterize when this bound is achieved. Furthermore, this result deduces the main result in [X. Duan and B.

On the Spectra of Commuting and Non Commuting Graph on Dihedral Group
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2017 Study about spectra of graph has became interesting work as well as study about commuting and non commuting graph of a group or a ring. But the study about spectra of commuting and non commuting graph of dihedral group has not been done yet.

Signless Laplacian spectral radius and Hamiltonicity
Linear Algebra and its Applications, 2010 For an \(n\) vertex of a graph \(G\), the matrix \(L^*(G)=D(G)+A(G)\) is the signless Laplacian matrix of \(G\), where \(D(G)\) is the diagonal matrix of vertex degrees and \(A(G)\) is the adjacency matrix of \(G\). Let \(\gamma(G)\) be the largest eigenvalue of \(L^*(G)\).

H$^+$-Eigenvalues of Laplacian and Signless Laplacian Tensors
, 2013 We propose a simple and natural definition for the Laplacian and the signless Laplacian tensors of a uniform hypergraph. We study their H$^+$-eigenvalues, i.e., H-eigenvalues with nonnegative H-eigenvectors, and H$^{++}$-eigenvalues, i.e., H-eigenvalues with positive H-eigenvectors.

Some graphs determined by their (signless) Laplacian spectra [PDF]
Czechoslovak Mathematical Journal, 2012 Let \(A(G)\) be the adjacency matrix of a graph \(G\) and let \(D(G)\) be the diagonal matrix whose entries are the degrees of the vertices of \(G\) in the order corresponding to the matrix \(A\). Then \(L(G) = D(G) - A(G)\) is called the Laplacian of \(G\) and \(Q(G) = D(G) + A(G)\) is the signless Laplacian of \(G\).

Some improved bounds on two energy-like invariants of some derived graphs
Open Mathematics, 2019 Given a simple graph G, its Laplacian-energy-like invariant LEL(G) and incidence energy IE(G) are the sum of square root of its all Laplacian eigenvalues and signless Laplacian eigenvalues, respectively. This paper obtains some improved bounds on LEL and
